Your solution is very unclear for me. Why don't you escape the dot character? Why do you use quotation marks and grouping in your regexp? This is working script:

<macrodef name="turnonproguard">
    <sequential>    
       <replaceregexp file="project.properties"
                match='proguard\.config=.*'
                replace='proguard.config=proguard.cfg'
                byline="false"/>
    </sequential>
</macrodef>

<macrodef name="turnoffproguard">
    <sequential>    
       <replaceregexp file="project.properties"
                match='proguard\.config=.*'
                replace='proguard.config='
                byline="false"/>
    </sequential>
</macrodef>

<target name="on">
    <turnonproguard/>
</target>

<target name="off">
    <turnoffproguard/>
</target>
